Job Description

You'll be joining a team of experienced senior developers, collaborating day-to-day on the design, build, and delivery of robust full-stack solutions for enterprise clients. This is a role where peer collaboration matters — you'll pair, review, and problem-solve alongside other seniors, share ownership of architectural decisions, and collectively raise the bar on code quality and technical direction. You'll also help mentor more other team members as the team grows. In this role, your key responsibilities will include: Design, develop, test, and maintain full-stack applications using C#/.NET across the back end and modern JavaScript frameworks on the front end. Lead technical design discussions and contribute to architectural decisions on new and existing systems. Translate client business requirements into well-documented technical solutions, including preparing system design documents. Build and optimise data-driven features backed by Microsoft SQL Server, including stored procedures, performance tuning, and integration with various reporting and ETL technologies. Take responsibility for code quality — perform code reviews, uphold coding standards, and champion unit testing and automated testing practices. Mentor and support junior and intermediate developers, sharing knowledge through pairing, reviews, and technical guidance. Participate in the full software development lifecycle: requirements gathering, estimation, implementation, deployment, and post-release support. Work directly with clients in the health sectors to troubleshoot issues, scope enhancements, and deliver responsive service. Contribute to continuous improvement of development practices, including CI/CD, source control workflows, and DevOps tooling. Help the team safely and effectively adopt modern productivity tools, including AI-assisted development tools where appropriate. #J-18808-Ljbffr
